    摘要： The present invention provides a refrigerant composition that is nonflammable, and ensures low LCCP and less burden on the environment. More specifically, the present invention relates a refrigerant composition containing difluoromethane (HFC32), pentafluoroethane (HFC125), and 2,3,3,3-tetrafluoropropene (HFO1234yf), the ratio of HFC32/HFC125/HFO1234yf being in a range surrounded by points (0/21/79 mass %), (16.6/25.3/58.1 mass %), and (0/28.4/71.6 mass %) in a ternary diagram of a refrigerant composition containing HFC32, HFC125, and HFO1234yf, and the composition essentially containing HFC32.
